  • FIG. 13 is a fragmentary section similar to that of FIG. 12 but with the valve shown in the open position.
  • a fluid-test apparatus generally designated 10 is shown to include a manifold generally designated 11, a plurality of gauge means generally designated 12, and a plurality of hose connections generally designated 13.
  • the manifold is defined by a body 14 having an internal manifold chamber 15.
  • a plurality of valve means generally designated 16 is provided for selectively controlling communication between the hose connections 13 and the manifold chamber 15.

  • Valve means 16 includes four valves 27, 28, 29 and 30 for controlling respectively fluid communication between the manifold chamber 15 and the hose connectors 19, 20, 21 and 22. In the illustrated embodiment, valves 27 and 30 further control communication between the gauges 17 and 18 and the manifold chamber 15.

  • hose connector 20 defines a vacuum connector which is larger than hose connectors 19, 21 and 22. More specifically, in the illustrated embodiment, the flow capacity of connector 20 is made to be at least approximately twice the flow capacity of the other hose connectors. As also seen in FIG. 1, hose 24 is larger than the other hoses, and in the illustrated embodiment, has a flow capacity of at least approximately twice that of the other hoses. Thus, where the hose 24 is utilized as a vacuum connection hose, concurrent flow from each of the hoses 23 and 26, which may be respectively connected to the high and low sides of the refrigeration system, may be effected for facilitated improved system servicing and testing.
  • valves 27, 28, 29 and 30 fluid communication between the respective connectors and the manifold chamber 15 is selectively controlled by the corresponding manually operable valves 27, 28, 29 and 30.
  • the respective valves may comprise diaphragm valves.
  • valve 29 As the valves are similar, a description of valve 29 as shown in FIG. 12 is applicable to each of the other valves.
  • the valve includes a flexible diaphragm 32 having a peripheral portion 33 sealingly urged against a shoulder 34 at the inner end of a recess 35 opening outwardly in the valve body 14. Inwardly of the diaphragm 32, the recess defines a valve chamber 36. As shown in FIG.
  • the manifold chamber 15 comprises a cylindrical chamber extending longitudinally of the manifold body.
  • the manifold body is provided with an inner recess 37 extending inwardly from the valve chamber 36 and intersecting the manifold chamber 15, as shown in FIG. 12.
  • the diaphragm 32 is urged sealingly across the recess 37.
  • the diaphragm is urged inwardly by a movable valve member 38 carried on a threaded stem 39 to the outer end of which is attached a handle 40.
  • a mounting cap 41 is threadedly secured in the recess 35 and is provided with a central passage 42 for coaxially threadedly mounting the valve stem 39.
  • An annular seal 43 may be provided extending between the cap 41 and the peripheral portion 33 of the diaphragm for effectively sealing the diaphragm to the manifold body.
  • the hose connections may have communication with the manifold chamber 15 through the recess 37 when the valve is in an open condition, such as shown in FIG. 13.
  • the manifold body is provided with an outer passage 44 extending inwardly from the hose connector, and an inner passage 45 extending from the outer passage 44 into communication with the valve chamber 36.
  • a pair of such inner passages may be provided for improved communication between the outer passage 44 and the valve chamber 36.
  • the inner passages of the valve connections at the opposite ends of the manifold body are angularly related to the axial centerline of the manifold chamber 15 in contradistinction to the inline arrangement thereof in connection with the valves 28 and 29, as illustrated in FIG. 8.
  • the upper inner passage 45u at the righthand end of the manifold body associated with valve 30 is disposed rearwardly horizontally of the manifold chamber 15 and communicates with a vertically upwardly opening outer passage 44u to which gauge 18 is connected.
  • the lower inner passage 45l is spaced clockwise from passage 45u approximately 120° and communicates with a downwardly opening outer passages 441 to which connector 22 is connected.
  • the lefthand end of the valve body is mirror image of the righthand end.
  • the manifold 11 may be supported by a hanger 46 which is secured to the manifold body by a threaded connector 47 received in a threaded recess 48 in the upper surface of the manifold body.
  • valve 27 may be provided with an identification plate reading "Low”
  • valve 28 may be provided with an identification plate reading "Vac”
  • valve 29 may be provided with an identification plate reading "Ref”
  • valve 30 may be provided with an idendification plate reading "High”.
  • gauge 17 may comprise a low reading gauge and gauge 18 may comprise a high reading gauge in conformity with the requirements for the particular use to which the apparatus is to be put.
  • the handles 40 comprise T-shaped handles providing facilitated manipulation of the valve member 38 and thereby providing further improved facilitated testing and servicing of the fluid system.
  • the valves may be readily serviced by the removal of the retainer cap 41 permitting the withdrawal of the seal 43 and diaphragm 32 and subsequent servicing or replacement as desired.
  • the invention comprehends an improved fluid-test apparatus construction wherein each of the hose connections is individually controlled by manually operable valve means and wherein communication of the gauges with the manifold chamber is controlled additionally by the hose connection valve means. Further, the gauges are connected to the hose connections in such a manner as to permit the gauges to have fluid communication with one or more of the hose connections at all times irrespective of the arrangement of the associated hose connection valve. While the apparatus provides such highly improved facilitated functioning, it is relatively compact and inexpensive and thus provides a substantial improvement in the fluid-test apparatus art.
